11. Summary of the new findings of the thesis

- Derive basic equations for resultant forces, higher for FGM toroidal shell segments with and without reinforced stiffeners within the framework of the third-order shear deformation theory (TSDT).

- Find out the closed-form of static critical load and post-buckling load-deflection curves for static stability problems; find out the explicit expressions of natural frequencies, nonlinear frequency–amplitude relations and the nonlinear differential equation of motion for vibration problems; find out the dynamic critical load according to the Budiansky-Roth criterion for the dynamical stability problems.

- Building numerical calculation programs to investigate the influence of geometrical dimensions, material distribution, elastic foundation parameters and temperature on the static stability, dynamic stability and vibration of the FGM toroidal shell segments.

12. Paratical applicability, if any: The research results can help in the design of FGM toroidal shell segments structures.

13. Further research directions, if any

- Study the static, dynamic stability, and vibration of shells made of other materials such as fiber-reinforced materials and carbon nanosheets FG-CNTRC, FG-GPLRC, auxetic...

- Study dynamic problems of shells under complex load, in complex environments such as under the effect of electric field, magnetic field, explosive load.

- Structures with cracks with different boundary conditions.

- Study static, dynamic stability, and vibration of the shell with nonlinear material properties.
